var obj = {};

setConfigurableReadOnly( obj, 'foo', 'bar' );

Notes

• Configurable read-only properties are enumerable.

Examples

var setConfigurableReadOnly = require( '@stdlib/utils/define-configurable-read-only-property' );

function Foo( name ) {
    if ( !(this instanceof Foo) ) {
        return new Foo( name );
    }
    setConfigurableReadOnly( this, 'name', name );
    return this;
}

var foo = new Foo( 'beep' );

try {
    foo.name = 'boop';
} catch ( err ) {
    console.error( err.message );
}
